PAPER-FOLDING MACHINE.

Application filed October a, 1923.. Serial No. 667,204.

invention relates to paper-folding ma chines, and more particularly tothe transverse feeding frame thereof. The. object of thisinvention isthe provision in a..paperfolding machine of a transfer appliance betweenthe horizontal and vertical folding rollswhich is less liable to becomeclogged with crumpled signatures and which may be more readily clearedtherefrom than is any appliance of this sortin the prior art.

Owing to the difficulty of obtaining com plete coact-ion between theinitial sets of fold ing rolls and the right-angle transfer mechanism ofa paper-folding machine, difficulty not infrequently is experiencedthrough the piling up of signatures in the transfer frame, whereby itbecomes jammed and the crum pled signatures are so tightly packedtherein that the frame must be taken out of the folding machine anddismantled in order to clear it of the tightly packed paper. Thisnecessarily involves considerable delay and expense which the presentinvention successfully obviates.-

In accordance with my improvements the transfer frame preferably ispivotally mounted adjacent to its lower edge within the paper-foldingmachine and a section thereof is movably mounted to insure better 31)operation and permit the ready removal of any signatures that mayaccidentally become jammed in said frame.

The details of this construction and advantages of its operation may bemore readi- 35 1y explained in connection with the accompanyingdrawings, wherein:

Figure 1 is a transverse sectional view of a paper-folding machineequipped with my improvements and illustrating the rightangle feedingmechanism in elevation.

"* drawings I have employed the same character of reference to indicatesimilar part-s.

Referring lnitially to Fig. 2, the foldlng and buckling rolls, a, b, cand (Z are shownin association with the throats of their coactingfolding plates'e and f, rearwardly broken away. From the rolls 0, d thesignature passes immediately to the rolls g, h for directing it into theright-angle transfer ap-' pliance which is the construction hereinspecificallyclaimed. a a

Said appliance comprises a frame 2'v pivotec. at 2' within the foldingmachine to swing through anarc approximately of from the full line tothe dotted line position; being held in its operative position by'meansof the links 2'" and thumb nuts it. The frame is provided with a seriesof rods 7" rigidly mounted beneath the throat member j and an opposinseries of rods 70 resiliently sup ported, together with the throatmember 70 by means of the coiled springs/c, as well shownv in Fig. 3.derstood that the right-hand section of the throat is yieldingly mountedin a manner to improve the operation of said transfer appliance byaffording it a slight resilience. Moreover, since the entirespring-mounted member may be depressed against the tension of thesprings, any jamming of crumpled signatures accidentally occurring belowthe IOlls g, It, will be localized at the throat member 70. v

WVhen this accidentally occurs, it is extremely easy to remove the massof signatures merely by releasing the links 2' and tilting the frameinto its dotted line position of Fig. 2. For this purpose the main frameof the folding machine is of rearwardly open type as indicated in Figs.1 and 2 in order to permit access to the downwardly tilted transferappliance. As the frame is made readily yielding, the crumpled paperdoes not become so tightly jammed as is the case with ordinary foldingmachines not equipped with my improvements, while no disassembling ofany portion of the machine is necessary in order to free it of theaccumulated signatures.

The grooved guide Z provided for the righthngle transfer appliance ismade vertically adjustable and is held in any adjusted position by theclamping screws Z. At the right ofsaid guide there are provided one ormore paired rolls on, m between which the lower edge of the signaturepasses inorder to impel it toward the right and effect a right-anglefold in the lateral fold ing plate n, shown broken away in Fig. 1.

Although Ihave illustrated the conical coiled springs k for resilientlysupporting From this, it will be un- Havin now described a 3aaer-t'oldin 1na-' chine equipped with the improvements of my presentinvention, which, however, is subject to more or less variations toadapt it for different classes of machines, I claim as new 10 and desireto secure by Letters Patent, to-

gether with such modifications as may be made therein by thoseordinarily skilled in the art, the following:

1. The combination with a paper-folding 53 machine, of a transferappliancev having relatively movable members, and resilient meanssubstantially as set forth.

2. The combination withv a paper-folding machine having horizontal andvertical folding mechanisms, of an interposed transfer appliancecomprising a frame liavingrelatively movable throat members, andyielding means associated with the movable throat member adapted toretain it in operative relation against such relative movement,substantially as set forth, 1

In testimony Wll-BIGOfI' do now affix my signature.
